Assertion : Carbon monoxide is extremely toxic. Reason : Carbon monoxide forms a stable complex with haemoglobin present in red blood cells.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Carbon monoxide \((\mathrm{CO})\) is an extremely toxic gas due to its ability to bind strongly with hemoglobin in the blood, forming carboxyhemoglobin, which reduces the blood's capacity to transport oxygen. So, option (1) is correct.

Water gas is produced by
1 Passing steam over red hot coke
2 Passing steam and air over red hot coke
3 Burning coke in excess of air
4 Burning coke in limited supply of air
Explanation:
Water gas \(\left(\mathrm{CO}+\mathrm{H}_{2}\right)\) is produed by passing steam over a bed of red hot coke at \(1000-1400^{\circ} \mathrm{C}\) \(\underset{\text { Coke }}{\mathrm{C}}+\mathrm{H}_{2} \mathrm{O} \rightarrow \underbrace{\mathrm{CO}+\mathrm{H}_{2}}_{\text {Watergas }} ; \Delta \mathrm{H}=+28 \mathrm{kcal}\)

When carbon monoxide is passed over solid caustic soda heated to \(200^{\circ} \mathrm{C}\), it forms
1 \(\mathrm{HCOONa}\)
2 \(2 \mathrm{CH}_{3} \mathrm{COONa}\)
3 \(\mathrm{Na}_{2} \mathrm{CO}_{3}\)
4 \(\mathrm{NaHCO}_{3}\)
Explanation:
When carbon monoxide is passed over solid caustic soda heated to \(200^{\circ}\), it forms sodium formate. \({\text{CO + NaOH}}\,\,\xrightarrow[{{\text{200}}^\circ {\text{C}}}]{{{\text{heated}}}}\,\,\,\mathop {{\text{HCOONa}}}\limits_{{\text{Sodium}}\,\,{\text{formate}}} {\text{ }}\)
